Abstract
The paper gives a brief introduction to laser interferometry used in device characterization in physical acoustics. Principal interferometric concepts (homodyne and heterodyne detection) are discussed, and some general capabilities and limitations of the concepts and current setups are presented. Data processing possibilities via Fourier methods are discussed. Application examples and recent results are reviewed briefly.
